Dynamics of the osmotic lysis of mineral protocells and its avoidance at the origins of life

open access: yesGeobiology, Volume 22, Issue 4, July/August 2024.
Abstract The osmotic rupture of a cell, its osmotic lysis or cytolysis, is a phenomenon that active biological cell volume regulation mechanisms have evolved in the cell membrane to avoid. How then, at the origin of life, did the first protocells survive prior to such active processes? The pores of alkaline hydrothermal vents in the oceans form natural

The Intermolecular Pauson‐Khand Reaction: Applications, Challenges, and Opportunities

open access: yesAdvanced Synthesis &Catalysis, Volume 366, Issue 4, Page 574-592, February 20, 2024.
Abstract The rapid assembly of complex organic molecules from simple and structurally diverse building blocks is a prevalent challenge in organic synthesis. The Pauson‐Khand reaction (PKR) is a method of choice for the construction of five membered rings that has historically been popularized as a late‐stage intramolecular cyclization method.
